Systemic Septicemia Overwhelms Late Nineteenth Century NonLethal Abdominal Gun Shot Wounds (GSW): President James A. Garfield (1831-1881) & Vincent Van Gogh (1853-1890)

U.S. President James A. Garfield (1831-1881) was a well-known and accomplished federal government servant who became the Twentieth President of the United States. Unfortunately, his presidency was interrupted by an assassin’s bullet six months after assuming the highest office in the land. Although the assassination attempt failed, it was sepsis that sealed his fate, not the assassin’s bullet. On September 19, 1881, after a seventy-nine-day battle to survive a non-lethal gunshot wound, President Garfield succumbed to septicemia which was caused by flagrant medical incompetence and hubris. Vincent van Gogh (1853-1890), now the most widely recognized and iconic artist, was an unknown artist at the time of his untimely death which occurred less than a decade later after President Garfield’s demise. Although President Garfield and Vincent van Gogh traveled significantly different pathways in their lives, the common thread that united them was their survivable GSW to their abdomens. This clinical scenario included bad medical wound management, motivation, and hubris which resulted in their deaths due to overwhelming systemic septicemia. President Garfield’s demise was the result of medical malfeasance and malpractice from all medical perspectives as understood from his medical history and detailed four-hour autopsy. Unsterilized multiple medical hands and unsterilized probing medical instruments facilitated the introduction of pathogens into the President’s body. In contrast, the septicemia associated with van Gogh’s death was the result of an acute infection due to the presence of an intra-abdominal bullet without an exit wound. The digital probing of van Gogh’s abdominal wound was conducted by Dr. Paul Gachet who harbored questionable motives against the artist. Nothing was mentioned if Dr. Gachet observed sterile procedures while digitally examining Vincent’s abdominal wound. Moreover, Dr. Gachet has been implicated by The Killing Vincent Project as a person of interest [1]. Did Dr. Gachet purposely facilitate Vincent van Gogh’s rapid demise to acquire Van Gogh’s, then unknown master artworks, for his collection while serving as the impetus to form the nucleus of the Gachet clandestine art forgery ring to copy these masterpieces? This question remains unanswered.

Operational-search detention (capture) as an object of legal regulation of operational investigative legislation

The subject of scientific research is the peculiarities of legal regulation of legal relations arising during the implementation of operational investigative detention (capture) of persons of operational interest during operational investigative measures provided for in Article 6 of Federal Law No. 144-FZ of August 12, 1995 "On operational investigative activities". The existing criminal procedural grounds for detention do not take into account the specifics and specifics of the activities of operational officers, which causes legal uncertainty in law enforcement practice. Taking into account the practical orientation of the use of operational-investigative detention (seizure), it should be noted that in the normative legal acts regulating the operational-investigative activities of the Department of Internal Affairs there are no norms regulating the grounds and conditions for the use of operational-investigative detention. These grounds should be taken into account and fixed in industry legislative acts, taking into account the specifics of the activities of operational units. Research methods: the method of comparative jurisprudence in the study of the grounds for detention; the method of comparative analysis in determining the compliance of the capabilities of operational units in the implementation of operational investigative detention. The author investigates the actual problems of law enforcement practice concerning the implementation by employees of operational units of such a measure of coercion as operational search detention (seizure). The scientific novelty lies in the analysis of regulatory legal acts regulating the grounds and procedure for detention; in proposals for improving operational investigative legislation. The main conclusions of the study are the need to supplement Article 6 of the Federal Law "On Operational investigative Activities" with the operational investigative measure "Operational investigative detention (seizure)", as well as to supplement Article 15 of the Federal Law with norms regulating the grounds and conditions, the procedure for conducting, the limits of the implementation of operational investigative detention (seizure).

Fake Face Images Detection and Identification of Celebrities Based on Semantic Segmentation

Convolutional Neural Networks (CNN) based detectors perform well in face manipulation detection, but are still limited by redundant information. Some methods focus on blending boundary to localize manipulation regions, discarding a part of useless information like background of image. But these methods still contain deceptive information such as facial regions without texture, which occupies resources and affects detection accuracy. Besides, these methods left out some features useful for identification. Therefore, this paper proposes a module by conducting semantic masks to guide detectors focus on face. The semantic segmentation masks focus on the facial features such as hair, eyes and other important areas, which can offer effective face identification high level semantic features. Our method uses masks as an attention-based data augmentation module and is simple for many DeepFake detection models to integrate. Experiments on multiple detectors with and without our module show our module's effectiveness. Without modifying their structural design, our approach enables CNN-based detectors to perform better. Especially, our method is well-suited for protecting the person of interest against face forgery.

Beyond Triplet Loss: Meta Prototypical N-Tuple Loss for Person Re-identification

Person Re-identification (ReID) aims at matching a person of interest across images. In convolutional neural network (CNN) based approaches, loss design plays a vital role in pulling closer features of the same identity and pushing far apart features of different identities. In recent years, triplet loss achieves superior performance and is predominant in ReID. However, triplet loss considers only three instances of two classes in per-query optimization (with an anchor sample as query) and it is actually equivalent to a two-class classification. There is a lack of loss design which enables the joint optimization of multiple instances (of multiple classes) within per-query optimization for person ReID. In this paper, we introduce a multi-class classification loss, <italic xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">i</i> . <italic xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">e</i> ., N-tuple loss, to jointly consider multiple ( <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"><tex-math notation="LaTeX">$N$</tex-math></inline-formula> ) instances for per-query optimization. This in fact aligns better with the ReID test/inference process, which conducts the ranking/comparisons among multiple instances. Furthermore, for more efficient multi-class classification, we propose a new meta prototypical N-tuple loss. With the multi-class classification incorporated, our model achieves the state-of-the-art performance on the benchmark person ReID datasets

SUPPLEMENTARY PARENTAL BENEFIT – THE MUM 4 + PROGRAMME – EXPECTATIONS AND REALITY

In this article the regulations of the act on parental supplementary benefit of January 30, 2019 are thoroughly analysed. Supplementary parental benefit is granted to a person who gave birth to and raised or only raised at least four children and did not acquire the right to a pension or a pension paid to this person by the pension authority is smaller than the lowest pension. One is entitled to the benefit mentioned herein only in the case of not having means of subsistence because of not pursuing or discontinuing employment as a result of raising minimum four children. Supplementary parental benefit is in no way related to making social security contributions, it is a benefit financed by the state budget, which in a supplementary or substitutional way is linked to old age. In the legal sense, it is not a pension, but a special non-contributory monetary benefit of discretionary nature, which is granted only on request of the person of interest based on the administrative decision of the president of the Polish Social Insurance Institution (ZUS) or the Agricultural Social Insurance Fund (KRUS).

Victim and Victim Support Staff Experiences of a Domestic Violence Electronic Monitoring Program in Australia.

This study investigates the experiences of victims of domestic violence (DV) involved in a bilateral electronic monitoring (EM) program. Semi-structured interviews were conducted with six victims whose associated person of interest participated in an EM program post-release, as well as 13 victim support staff. Thematic analysis revealed seven themes: (1) Safety and validation, (2) Initial anxiety, (3) Minimal intrusion on daily life, (4) Psychological relief and feelings of safety, (5) Freedom to engage in daily activities, (6) Post-EM concerns for safety, and (7) An effective deterrent for some, but not for all. Overall, the experiences reported by victims and support staff were positive and evident of victim-centricity. The main defining experience of the DVEM program for victims was improved feelings of safety during the program and increased autonomy and confidence in going about their daily activities. However, there is an urgent need to consider post-EM safety of victims.

Casework-related DNA transfer on footwear in consideration of the shedder status

DNA evidence on shoes can play an important role in solving a variety of crimes. We investigated the transfer, persistence, prevalence and recovery of DNA (DNAtppr) on shoes (sneakers) and their soles in realistic handling scenarios taking into account the shedder status. This study aims to increase the understanding of the expected composition of DNA profiles and their probative value, providing a basis for activity level assessments. Samples were analyzed using a direct lysis method, suggesting its versatility and increasing the DNA typing success compared to previous studies on footwear. The data showed surface-dependent background DNA (bDNA) levels on shoe soles and prevalence of bDNA on the upper parts of the shoe. The owner of the shoe was allocatable to the mixture for almost every shoe and sampling location. Alternating scenarios of shoe handling were simulated through different pairs of shedders to distinguish shoe owner and subsequent user. Secondary users were attributable to DNA mixtures regardless of shedder status after wearing shoes a single time. The influence of the shedder status follows specific trends in this context. However, particularly intermediate shedders show inconsistent results. The prevalence of bDNA appears to have a greater effect on the impact of the shedder status on DNA profile composition than previously reported. The data help researchers to better resolve suspect statements and determine if a person of interest wore the shoes relevant to the investigation.

A novel computational strategy to predict the value of the evidence in the SNP-based forensic mixtures.

This study introduces a methodology for inferring the weight of the evidence (WoE) in the single nucleotide polymorphism (SNP)-typed DNA mixtures of forensic interest. First, we redefined some algebraic formulae to approach the semi-continuous calculation of likelihoods and likelihood ratios (LRs). To address the allelic dropouts, a peak height ratio index (“h,” an index of heterozygous state plausibility) was incorporated into semi-continuous formulae to act as a proxy for the “split-drop” model of calculation. Second, the original ratio at which a person of interest (POI) has entered into the mixture was inferred by evaluating the DNA amounts conferred by unique genotypes to any possible permutation of any locus of the typing protocol (unique genotypes are genotypes that appear just once in the relevant permutation). We compared this expected ratio (MRex) to all the mixing ratios emerging at all other permutations of the mixture (MRobs) using several (1 - χ2) tests to evaluate the probability of each permutation to exist in the mixture according to quantitative criteria. At the level of each permutation state, we multiplied the (1 - χ2) value to the genotype frequencies and the h index. All the products of all the permutation states were finally summed to give a likelihood value that accounts for three independent properties of the mixtures. Owing to the (1 - χ2) index and the h index, this approach qualifies as a fully continuous methodology of LR calculation. We compared the MRs and LRs emerging from our methodology to those generated by the EuroForMix software ver. 3.0.3. When the true contributors were tested as POIs, our procedure generated highly discriminant LRs that, unlike EuroForMix, never overcame the corresponding single-source LRs. When false contributors were tested as POIs, we obtained a much lower LR value than that from EuroForMix. These two findings indicate that our computational method is more reliable and realistic than EuroForMix.

A Hybrid Neural Network Architecture to Predict Online Advertising Click-Through Rate Behaviors in Social Networks

People connected by huge-size socialnetworks are highly dependent on recommendation systems to discover interesting persons, contents, and commodities. Extracting user interests and modeling their evolutions from user historical behavior are vital for algorithms to judge whether users are interested in given persons and items. The existing methods have two shortcomings: firstly, they do not have the high-order ability to process temporal sequences, which leads to their inability to mine the evolution of user interests; secondly, the models take full large-scale information of items as input, which causes a severe problem of overfitting. Thus, we propose a new hybrid neural network, DGRU, which integrates Factorization-Machine Based Neural Network (DeepFM) and Gated Recurrent Unit Neural Network (GRU). The DeepFM component is responsible for performing the autonomic feature combination, and the GRU component is designed to model user interests and evolutions. The GRU component is fed with a series of 1 and 0 representing user click behaviors. It contains information on what users like and dislike. Moreover, the conciseness of the format is helpful to avoid the problem of overfitting. Experiments on three real datasets demonstrated that the proposed model has a better CTR prediction performance and robustness than the state-of-the-art models.

Pose2Sim: An End-to-End Workflow for 3D Markerless Sports Kinematics-Part 1: Robustness.

Being able to capture relevant information about elite athletes’ movement “in the wild” is challenging, especially because reference marker-based approaches hinder natural movement and are highly sensitive to environmental conditions. We propose Pose2Sim, a markerless kinematics workflow that uses OpenPose 2D pose detections from multiple views as inputs, identifies the person of interest, robustly triangulates joint coordinates from calibrated cameras, and feeds those to a 3D inverse kinematic full-body OpenSim model in order to compute biomechanically congruent joint angles. We assessed the robustness of this workflow when facing simulated challenging conditions: (Im) degrades image quality (11-pixel Gaussian blur and 0.5 gamma compression); (4c) uses few cameras (4 vs. 8); and (Cal) introduces calibration errors (1 cm vs. perfect calibration). Three physical activities were investigated: walking, running, and cycling. When averaged over all joint angles, stride-to-stride standard deviations lay between 1.7° and 3.2° for all conditions and tasks, and mean absolute errors (compared to the reference condition—Ref) ranged between 0.35° and 1.6°. For walking, errors in the sagittal plane were: 1.5°, 0.90°, 0.19° for (Im), (4c), and (Cal), respectively. In conclusion, Pose2Sim provides a simple and robust markerless kinematics analysis from a network of calibrated cameras.

Age Determination from Coracoid Process of Shoulder Joint in Males of Central India

There is no statistical data to establish variation in coracoids process fusion of shoulder joint in males in central India population. This significant oversight can lead to exclusion of persons of interest in a forensic investigation. Coracoid process fusions in males were analyzed on radiological basis to assess the range of variation of coracoids process fusion at each age. In this study the X ray films of the subjects were divided into three groups on the basis of degree of fusion. Firstly, those which were showing No Fusion )N), secondly those showing Partial Union )PC), and thirdly those showing Complete Fusion )C). Observations made were compared with the previous studies.

The comparison of DNA mixture profiles with multiple persons of interest

When we compare a DNA mixture profile to a single person of interest, there are often just two competing explanations considered, and the comparison of how likely these are to lead to the observed mixture is summarized by a likelihood ratio. However, in more complex cases this does not suffice, e.g., when there are multiple persons of interest. One can then compute several likelihood ratios, corresponding to several pairs of hypotheses, and subsequently decide which one(s) to report. This may lead to the computation of a rather large number of such likelihood ratios. In this article we advocate a systematic approach that starts by describing all relevant hypotheses. For each hypothesis, we then compute its likelihood (i.e., the probability to see the genetic data if the hypothesis is true). Based on the likelihoods of all considered hypotheses, one can then make a summary of the findings to report. This may be on the level of the considered hypotheses and/or with likelihood ratios per person of interest. We illustrate with several examples how this approach assists interpretation. The likelihoods summarize how the trace can help to distinguish between the considered hypotheses, in the sense that they transform the prior odds on them into posterior odds, without having to assign prior probabilities on the hypotheses for the calculation of the likelihoods themselves. On the other hand likelihood ratios (LR’s) for individual PoI’s cannot be obtained without these priors. In many cases these LR’s will be quite insensitive to the choice of prior probabilities but in other cases they will be; we give examples of both.We argue that the table of likelihoods of the considered hypotheses is a more natural analog of the LR provided in the simple case with one PoI and two considered hypotheses, compared to the computation of a LR per PoI. We end with a discussion of the choice of prior probabilities, of the existing recommendations for this situation, and on reporting.

Practical strategies for qualitative inquiry in a virtual world.

The aim of this article is to provide practical strategies for maintaining methodological rigour in executing a virtual qualitative study. Strategies are based on evidence from existing research about virtual qualitative methods and on the strategies used by the authors to convert a planned in-person qualitative, grounded theory study to an entirely virtual grounded theory study during the COVID-19 pandemic. The study began in-person in September 2019 and was converted to virtual in March 2020. Virtual data collection was completed in September 2020. This article provides a case exemplar of virtual adaptations made to a study underway when the pandemic rendered all in-person research impractical and potentially dangerous. The strategies discussed are based on our own experiences and the supporting theoretical assumptions of qualitative research, specifically grounded theory methods. Nursing scholars conducting qualitative inquiry may find these strategies helpful in continuing research activities during periods of limited access to the phenomena or persons of interest. Furthermore, these strategies allow nursing scholars to conduct rigorous, in-depth research without geographical limitations, providing greater possibilities for international collaborations and cross-institution research. Despite novel challenges, methodological adaptations that are carefully planned and purposeful allow qualitative and non-qualitative scholars to continue research activities in a fully virtual manner. This case exemplar and discussion provide practical strategies for qualitative scholars to consider while planning new studies or converting an in-person study to a virtual one. Despite the in-person nature of in-depth qualitative inquiry, a historic pandemic and a changing research environment require qualitative researchers to adapt to virtual methods while still conducting high quality, methodologically rigorous research. Qualitative scholars can use the strategies presented here to continue rigorous qualitative inquiry despite limited access to phenomena or persons.

Smart Surveillance System using Face Tracking

The face is seen as a key component of the human body, and humans utilise it to identify one another. Face detection in video refers to the process of detecting a person's face from a video sequence, while face tracking refers to the process of tracking the person's face throughout the video. Face detection and tracking has become a widely researched issue due to applications such as video surveillance systems and identifying criminal activity. However, working with videos is tough due to problems such as bad illumination, low resolution, and atypical posture, among others. It is critical to produce a fair analysis of various tracking and detection strategies in order to fulfil the goal of video tracking and detection. Closed-circuit television (CCTV) technology had a significant impact on how crimes were investigated and solved. The material used to review crime scenes was CCTV footage. CCTV systems, on the other hand, just offer footage and do not have the ability to analyse it. In this research, we propose a system that can be integrated with the CCTV footage or any other video input like webcam to detect, recognise, and track a person of interest. Our system will follow people as they move through a space and will be able to detect and recognise human faces. It enables video analytics, allowing existing cameras to be combined with a system that will recognise individuals and track their activities over time. It may be used for remote surveillance and can be integrated into video analytics software and CCTV security solutions as a component. It may be used on college campuses, in offices, and in shopping malls, among other places.

Incidence of Early Police Contact Among Children With Emerging Mental Health Problems in Australia

In adulthood and adolescence, mental health vulnerability is known to be associated with risk of criminal justice system contact as both a perpetrator and survivor of crime, but whether this association is apparent early in child development is unknown. Prevention of poor outcomes, including repeated contact with the criminal justice system, relies on the identification of vulnerability early in life and at the start of such contact. To ascertain whether children with emotional or behavioral problems and general developmental vulnerabilities are at an increased risk of subsequent contact with police as a person of interest, a survivor of crime, or a witness. This cohort study used routinely collected data from the New South Wales Child Development Study in Australia. The cohort was composed of children who entered full-time schooling in New South Wales in 2009, had complete data for the emotional maturity domain of the Australian Early Development Census, and had no police contact before January 1, 2009. The children in the cohort were followed up until the age of 13 years. Data were analyzed from October 17, 2019, to May 13, 2020. Emotional or behavioral problems and developmental risk profiles derived from the teacher-rated Australian Early Development Census. Incidence rates of police contact (as a person of interest, survivor of crime, or witness) were derived from the New South Wales Police Force Computerised Operational Policing System. A total of 79 801 children (40 584 boys [50.9%]; 2009 mean [SD] age, 5.2 [0.37] years) were included. Children with teacher-identified emotional or behavioral problems at school entry had an incidence rate of police contact (for any reason) that was twice that of children without such problems (unadjusted hazard ratio [HR], 2.14; 95% CI, 1.94-2.37). Contact with police as a survivor of crime was most commonly recorded (7350 [9.2%]), but the strength of the association was greatest between emotional or behavioral problems and police contact as a person of interest (unadjusted HR, 4.75; 95% CI, 3.64-6.19). Incidence of police contact as a person of interest was high for children with a pervasive developmental risk profile (unadjusted HR, 13.80; 95% CI, 9.79-19.45). This study found an association of emerging emotional or behavioral problems and developmental vulnerabilities with increased risk of police contact for any reason among young children, suggesting that this well-known association in adults and adolescents can be identified at an earlier developmental stage. These findings support primary and secondary interventions to prevent police contact early in life and to target the earliest contacts with the criminal justice and educational systems.

Interpretation of DNA data within the context of UK forensic science — investigation

This article is the second part of a review of the interpretation of DNA data in forensic science. The first part describes the evaluation of autosomal profile for criminal trials where an evidential weight is assigned to the profile of a person of interest (POI) and a crime-scene profile. This part describes the state of the art and future advances in the interpretation of forensic DNA data for providing intelligence information during an investigation. Forensic DNA is crucial in the investigative phase of an undetected crime where a POI needs to be identified. A sample taken from a crime scene is profiled using a range of forensic DNA tests. This review covers investigation using autosomal profiles including searching national and international crime and reference DNA databases. Other investigative methodologies described are kinship analysis; familial searching; Y chromosome (Y-STR) and mitochondrial (mtDNA) profiles; appearance prediction and geographic ancestry; forensic genetic genealogy; and body identification. For completeness, the evaluation of Y-STRs, mtDNA and kinship analysis are briefly described. Taken together, parts I and II, cover the range of interpretation of DNA data in a forensic context.

Examining the overlap of young people’s early contact with the police as a person of interest and victim or witness

There is known to be considerable overlap among the victims and perpetrators of crime. However, the extent of this overlap early in life among children and young adolescents is not clear. We examined the sociodemographic profiles of young people who had early contact with police regarding a criminal incident as a person of interest, victim and/or witness, as well as the patterns of multiple police contact types from birth to 13 years of age. Data were drawn from a longitudinal, population-based sample of 91,631 young people from New South Wales, Australia. Among the 10.6% (n = 9677) of young people who had contact with police, 14.4% (n = 1393) had contact as a person of interest and as a victim and/or witness on two or more separate occasions. The most common first contact type was as a victim/witness, but those children with a first contact as a person of interest were most likely to have at least one further contact. Young people with both types of police contact were younger at first police contact, were more likely to reside in a socioeconomically disadvantaged area, and to be recorded as having an Aboriginal and/or Torres Strait Islander background. Our findings demonstrate that, by 13 years of age, 1 in 10 young people had been in early contact with police and that a minority have contact with the police as both a person of interest and a victim/witness. These young people may represent a particularly disadvantaged group in the community who are likely to be at risk of future adversity, including repeated contact with the criminal justice system.

Interpretation of DNA data within the context of UK forensic science - evaluation.

Forensic DNA provides a striking contribution to the provision of justice worldwide. It has proven to be crucial in the investigative phase of an unsolved crime where a suspect needs to be identified, e.g. from a DNA database search both nationally and internationally. It is also a powerful tool in the assignment of evidential weight to the comparison of a profile of a person of interest and a crime scene profile. The focus of this document is the evaluation of autosomal profiles for criminal trials in the UK. A separate review covers investigation and evaluation of Y-STR profiles, investigation using autosomal profiles, kinship analysis, body identification and Forensic Genetic Genealogy investigations. In less than 40 years, forensic DNA profiling has developed from a specialist technique to everyday use. Borrowing on advances in genome typing technology, forensic DNA profiling has experienced a substantial increase in its sensitivity and informativeness. Alongside this development, novel interpretation methodologies have also been introduced. This document describes the state of the art and future advances in the interpretation of forensic DNA data.
